Apollo 040 problem

[LuisTHE]

 Hello,i have a question about the Apollo 040,lately i´ve been having crashes after the amiga is on for a few minutes,my 040 does have fan,but i think that the FPU or the MMU might be malfunctioning.
 So my question is,if the FPU or MMU are not functioning properly,will they cause crashes?
 Can i remove the FPU and MMU cpu,and will my board still work? :-D

 Yes,i have the mmu.library,the 68040.library that identifies the cpu and the fpu,i always thought that there could be a fpu.library,but i never found it.
 Maybe it needs more cooling,as i´ve said before,the amiga runs smoothly until 30 minutes or so and then it hangs.
 It made my HD unvalidated many times,it is a annoying! :-D

  I have thought about the 5v,could it they be damaged,after all it is an old card. :-D
